[U-Boot] [PATCH v2 5/7] bootcount: spl: Extend SPL to support bootcount incrementation

[Lukasz Majewski]

This patch adds support for incrementation of the bootcount in SPL.
Such feature is necessary when we do want to use this feature with
'falcon' boot mode (which loads OS directly in SPL).

Signed-off-by: Lukasz Majewski <lukma at denx.de>

Changes in v2:
- New patch - as suggested by Stefan Roese - bootcount_inc() is called
  in common SPL code (./common/spl/spl.c), so other boards can also
  reuse it without modification
